Specification forming part of Letters Patent No. 152,885, dated July 7, 1874 application filed June 2, 1874.

To all whom it may concern Be it known that I, RALPH S. L. WALSH, of Washington, District of Columbia, have invented certain new and useful Improvements in Combined Bottle-Syringe and Stopper; and I do hereby declare that the following is afull, clear, and exact description thereof, reference bein g had to the accu mpanyin g drawin gs, and to letters of reference marked thereon, which form part of this specification.

The nature of my invention consists in the combination of a rubber bulb, adapted to be applied to the neck of a bottle, with a nozzle or tube and a valve, arranged to operate substantially as hereinafter set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, which represents a vertical section of my invention applied to the neck of a bottle.

A represents a rubber bulb of any suitable dimensions, provided at its upper end with a suitable nozzle or tube, B. This tube may be constructed to discharge either a single current, jet, or spray, or there may be adjustable attachments to discharge the liquid in any form desired. A suitable distance above the lower end, within the bulb A, is inserted a disk, (3, of wood or other suitable material. This disk is slightly concave or grooved circumferentially, and held in the bulb by means of aring, a, placed around the exterior of the neck of the bulb, and pressing the same into the groove or concave on the disk. Theextreme lower end, d, of the bulb is to be drawn over the usual flange, b, on the neck of a bottle, E, thereby holding the bulb and disk on the bottle, and forming a tight joint. There is a central aperture in the disk 0, and on the upper side thereof is secured a weighted valve, D, to close said aperture.

I do not wish to confine myself to this arrangement or method of attaching the valve to the inside of the bulb, as it is evident that the valve-seat may be modified without inthe least departing from the principle of my in vention; for instance, the bulb may be constructed with an internal flange or collar. In any event, however, the valve must open toward the top-or center of the bulb, thus admitting the liquid, but effectually preventing its escape, except through the nozzle, when the bulb is pressed. By inverting the bottle E the valve D is opened by the pressure of the fluid, which passes through and fills the bulb. By now returning the bottle to its proper po= sition, the valve D closes, leaving the fluid in the bulb. By squeezing or pressing the bulb the fluid therein is forced out of the nozzle B, either in the form of one or more jets, or as spray, according to the character of the nozzle used. After use, the nozzle 13 may be removed and a suitable plug or cap inserted in its place, completely stopping the bulb and bottle, thereby preventing any loss of fluid renliaining in the bulb or any flow from the bott e.

The advantages of my invention are as fol lows: First, by simply inverting the bottle the syringe will be filled; second, with this syringe the urethra may be filled to its utmost capacity without withdrawal of the syringe or escape of any fluid previously thrown in; third, there being no piston to work unevenly,

there is no risk of wounding or irritating the urethra by the nozzle.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

The combination of the bulb A, adapted to be applied to the neck of a bottle, nozzle B, and valve D, said valve being arranged to open inwardly, as and for the purposes herein set forth.

In testimony that I claim the foregoing as my own, I affix my signature in presence of two witnesses.

RALPH S. L. WALSH.
